Ok, great.
Sometimes walls are (partly) at an angle. Are there tags to handle this?
Hi. Is the rendering of multipolygons still support?
P.S. I mean segmented multipolygons which consists of many different parts (ways).
cmif4 Thanks for the answer. I have problem with this area
All buildings (even simple parallelepiped) is not rendered.
Something there crash our building server, we’re working on a solution, please do not try to fix the area on OSM side we’re using it as a test case.
Now it’s alright. Thank you very much for fast reaction and solution! 
Hi cmif4,
what´s about rendering of changes? Do you have technical problems?
I try to teach some young people in this city
http://demo.map.f4-group.com/#lat=51.2201360&lon=18.5711863&zoom=18&camera.theta=69.4&camera.phi=44.404&goto_f4map=goto_f4map
how to make 3d models, but when we wait longer than 1 day for rendering, they re not especially enthusiastic… 
Best regards,
Marek
hello !
We’ve been having problems with osm synchronisation since last week and are actively working on it.
Sorry for any inconvenience !
Could yuo inform us, when the problem is fixed?
For now the server is 5 days late on OSM synchronization, we’ll keep you informed here when we’ll found a solution.
Marek,
I haven’t tested it yet, but there is a JOSM plugin for 3D rendering: http://wiki.openstreetmap.org/wiki/Kendzi3d
I hope it can help in visualizing the results.
I’m sure Marek is already using Kendzi3D but he wants to see the result in F4Map for the other features.
Dear jgpacker, thank You for the information.
Kendzi has created this tool according to my specifications. We are good friends. 
And yes: I would be happy to see changes 1 hours after modelling in F4Map.
Dear cmif4, what´s about incremental update?
We’re already doing incremental updates but our server is heavily charged by some evil processes that stuck the OSM Synchronization we’re gathering the alliance forces to get it away from our galaxy as soon as possible.
server is starting to catch up, it’s still 4 days late, and it should take approximately 4 days to catch up, so it should be in sync sometime during sunday
Thanks Cactusbone!
Suggestion:
use for building=garage without height=* as default height=3 meter
use for building=greenhouse without height=* as default height=4.5 meter
We’re already using mapping tables for height generation :
50 → 75 meters for [‘tower’, ‘skyscraper’]
10 → 20 meters for [‘apartments’, ‘dormitory’, ‘hospital’, ‘hotel’, ‘commercial’, ‘industrial’, ‘warehouse’, ‘church’, ‘cathedral’, ‘civic’, ‘public’, ‘barn’, ‘hangar’]
3 → 4 meters for [‘roof’, ‘canopy’, ‘cabin’, ‘shed’, ‘hut’, ‘garage’, ‘garages’]
7 → 10 meters for other values
Greenhouse automatically uses glass material on both walls and roofs
I know
I did it already 2008 for 3D model of Hamburg: http://www.hamburg.de/contentblob/407336/data/3-d-stadtmodell.pdf
I introduced the term “Level of detail”. In LOD 1 is the representation of buildings only by use of building outline and estimated height depend on use.
I defined also the table with heights for different building uses based on realistic values for heght.
OSM definition allows very detailed and more realistic height estimation. I give you simply my experience.
Btw:
Realistic LOD 2 from Hamburg - http://www.maxon.net/uploads/pics/02_02.jpg
It works now.
- Following polygon are not rendered:
http://www.openstreetmap.org/way/278201017
http://www.openstreetmap.org/way/168324687
What´s the reason?
- This city: http://www.openstreetmap.org/#map=15/51.2200/18.5714 is an experiment area with some young users from the geodesy gymnasium Wielun.
Is it possible to render this area in shorter time periods? Also as a kind of experiment for You.
In the psychological point of view is it difficult to motivate young people during such actions when the results are visible after 24 hours.
Hi Marek,
both ways are not valid in JOSM (self intersecting polygons) i fixed them a few minutes ago.
